7. Select the time to apply the update. After WebPRo uploads
the Firmware Package file, the system can reset and switch to
the new version immediately or at a scheduled time and date.
The time specified is relative to the time on the KTS instead of
the PC that WebPro was run from. The technician must
consider time zone differences when scheduling updates.
8. Click Start to begin uploading the Firmware Package file. The
progress bar indicates the progress of the upload.
9. Click OK when asked if you are sure you want to proceed.
10. The update procedure may take a few minutes to complete.
Do not interact with the browser window until the update is
complete. Do not reset the CPU until the update is complete.
11. After the upload is complete, a complete message is displayed
in the WebPro browser window.
When immediately is selected for the Schedule Update section,
reset and switching versions takes place at the beginning of the
next minute (e.g., if upload completes at 4:36:29 PM, reset
takes place at 4:37:00 PM).
12. After a remote upgrade, the Compact Flash must remain in the
system. The CPUII( )-U10 ETU now boots up from the
Compact Flash, not the onboard Flash memory. If the
Compact Flash is removed, the system boots from the old
version in the onboard Flash.
Two versions of firmware are kept on the
Compact Flash
.
One version is the current version that the CPU booted from.
The other version is the new version to be used at the next
bootup. If bootup fails, the system can revert to the older
version.
13. Connect with WebPro again and go to the System
Configuration section of the Home Page to verify that the
system upgraded to the new version.
14. The Firmware version underneath Cabinet 1 should look like
the following: CPU: xx.xx(America). The on site technician
can press F3 from any multiline terminal.
